The core advantage of touch display module lies in integrating display and control into a single interface, serving as an interactive platform that combines “information output” and “command input.” Incorporating touchscreens into modern seed drills not only enhances the equipment's aesthetics but also improves operational precision and efficiency.
Its functionality is primarily reflected in the following aspects:
1. Parameter Settings at a Glance
Purpose: Replaces cumbersome physical knobs and buttons. Before seeding, the operator sets key parameters like row spacing, plant spacing, and seeding depth directly on the screen, much like operating a large smartphone.
2. Status Monitoring on a Single Screen
Purpose: During seeding operations, the screen serves as the machine's “eyes.” It graphically displays real-time information:
Which row is being planted: Each row is represented by a distinct colored line.
Which row is clogged: If a row becomes blocked, its corresponding line immediately turns red and flashes an alert.
Seed/fertilizer remaining: Clear progress bars or percentages show remaining quantities in the hopper, with advance warnings when levels get low.
3. Navigation and accounting: Stay informed
Purpose: Integrates GPS to display the planter's travel path, direction, and A/B navigation lines on the screen.
Core Functional Advantages of Touch display module on Planters
1. Centralized Interface: Consolidates scattered gauges, indicator lights, and buttons onto one screen for a clean layout, reducing driver information overload.
2. Efficient & Precise Settings: Replaces imprecise mechanical knobs with digital keypad input for faster, more accurate parameter adjustments.
3. Intuitive and User-Friendly Interaction: Graphical interfaces in Chinese (or local languages) lower the learning curve, enabling even novice operators to master controls quickly.
4. High Flexibility: When upgrading or modifying machine functions, new settings or display information can be added simply by updating the screen software—no hardware layout changes required.
5. Space Savings: Significantly reduces physical space occupied by in-cab control panels.
Key practical limitations to consider: In harsh environments like seeders, touchscreens must address glare resistance (visibility in bright light), vibration resistance, wide temperature operation, and sensitivity for gloved operation. Current mainstream industrial-grade touchscreens overcome these challenges through high-brightness LCDs, resistive screens, capacitive screens with glove operation modes, and ruggedized construction. Thus, their functional applications are entirely grounded in practical requirements and are technically feasible.
